Entropy production estimates for the polyatomic ellipsoidal BGK model

Entropy production estimates for the polyatomic ellipsoidal BGK model

We study the entropy production estimate for the polyatomic ellipsoidal BGK model, which is a relaxation type kinetic model describing the time evolution of polyatomic particle systems. An interesting dichotomy is observed between 0
